[WHLSL] Improve test suite type safety
https://bugs.webkit.org/show_bug.cgi?id=189502

Patch by Thomas Denney <[email protected]> on 2018-09-19
Reviewed by Myles C. Maxfield.

Each of the 'makeT' functions now call the relevant cast function on the
value before hand. The checkNumber function has also been removed and
its uses have been replaced with functions that also check the type.
Some of the arithmetic checks have been updated to reflect that the
casts happen outside of WHLSL evaluation. Other tests have also been
updated to reflect that some values cannot be precisely expressed in
32-bit floating point.

* WebGPUShadingLanguageRI/Casts.js:
(castToBool): Added.
(castAndCheckValue): Added.
(isBitwiseEquivalent): Moved from Intrinsics.js.
* WebGPUShadingLanguageRI/Intrinsics.js: Ditto.
* WebGPUShadingLanguageRI/SPIRV.html: Update depdencies.
* WebGPUShadingLanguageRI/Test.html: Ditto.
* WebGPUShadingLanguageRI/Test.js: Update makeT functions to do a cast
and check the result. Some tests were also updated to reflect the change
in the behavior of these functions.
* WebGPUShadingLanguageRI/index.html: Update dependencies.
